The power of reflection is the most powerful skill you’ll learn.

Nobody said it’d be easy, they just promised it would be worth it.

A hero is no braver than an ordinary man, but he is braver five minutes longer.

Your limitation - its only your imagination.

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

I think, therefore I am.

If you want to succeed, double your failure rate.

Failure is NOT your destiny. Failure is the key to success.

Don't expect to be good at maths or understand things straight away. Be patient and persistent. Rome wasn't built in a day, but they worked on it every single day. 

Don’t practice until you get it right, practice until you can’t get it wrong.

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

Instead of finding reasons why you can't, find reasons why you can.

In order to become better than anybody else you must first become better than yourself.

Everything you want is on the other side of fear

It is never too late to turn an unproductive day into a productive one.
